Final answer:
Job fairs allow potential applicants to discuss openings with employers without having a job application/résumé on file.
Step-by-step explanation:
The recruitment method that offers the opportunity for potential applicants to discuss openings with employers without having a job application/résumé on file is job fairs.
Job fairs are events where multiple employers gather in one location to attract and interact with potential candidates. These events provide a platform for job seekers to engage with employers directly, ask questions, and gather information about available positions.
Unlike other recruitment methods that require submitting a job application or having a résumé on file, job fairs provide an opportunity for face-to-face communication and networking with employers, making it easier for potential applicants to express their interest and learn more about job openings.
